Title: Improvements in or relating to airships and methods of operating the same
IPC: B64B1/60
Filed: 1927-01-27
Abstract: 266,310. Luftschiffbau Zeppelin Ges., (Assignees of Lempertz, E.). Feb. 18. 1926, [Convention date]. Aerostats. - In order to avoid variations of buoyancy as fuel is consumed, an airship is provided, in addition to the lifting gas cells, with cells for a fuel gas of substantially the same density as air so that no static forces are imposed on the airship by reason of its fuel, the amount of lifting gas being sufficient only to support the useful load and the aircraft structure. Ethylene or mixtures of other gaseous hydrocarbons may be used as fuel gas. The volume of the lifting gas cells is distributed along the airship in direct proportion to the loading of the structure and the fuel gas cells are disposed in the remaining spaces within the hull. The necessity for the provision of special parts for supporting the fuel load from the upper part of the airship is obviated. The fuel gas may be contained in cells e beneath the lifting gas cells d at normal pressure or it may be maintained at a higher pressure by air ballonete or by the pressure of the gas cells, particularly when a gas slightly lighter than air is employed. When not under initial pressure the fuel gas is fed to the engines by suction. The fuel gas chambers are arranged to provide additional expansion space for the lifting gas with the progressive consumption of fuel. A gas heavier than air may be employed if stored under appropriately reduced pressure. Means for burning small quantities of liquid fuel or lifting gas may be provided in order to compensate for accidental variations of buoyancy.

Title: Superconducting solenoid
IPC: H01F6/02
Filed: 1965-01-20
Abstract: 1,045,512. Super-conductor devices. RADIO CORPORATION OF AMERICA. Jan. 20, 1965 [Feb. 28, 1964], No. 2488/65. Heading H1K. As shown a superconductor magnet comprises a stack of thin discs 12 of thermally conductive material such as copper, gold, aluminium or silver, interleaved with thin discs 14 each comprising a platinum substrate 16 having concentric rings of niobium-tin alloy deposited on both of its faces, Fig. 7 (not shown). The stack is mounted in a press 24 and the assembly placed in an external magnetic field and cooled below the critical temperature of niobium-tin alloy. On removal of the external magnetic field the magnet retains a strong residual field as long as the temperature is maintained below the critical temperature. The niobium-tin rings may be produced by heating the substrate in an atmosphere of niobium chloride, tin chloride and hydrogen and dividing the deposited layers into rings by sandblasting, etching with hot alkali, or scratching away the superconductive material. Niobium-gallium and vanadium-silicon alloys may also be used as the superconductive material.

Abstract: 479,389. R÷ntgen ray diaphragms. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 30, 1937, No. 2781. Convention date, Jan. 31, 1936. [Class 98 (i)] A Potter-Bucky grid for intercepting secon dary radiation and permitting exposures of considerably less than one second com prises alternate strips of ray - impermeable and ray - permeable material, e.g. lead and wood, there being a least 30 strips per inch Grids having 33 and 44 strips per inch per mit exposure times of <1>/ 5th and <1>/20th second respectively. The grid ratio (i.e. ratio of depth, of a grid passage to width thereof) may be not more than 6, and the planes of the strips are disposed so that they intersect in known manner in a common focal line. The grid may be made by forming a laminated sheet consisting of alternate layers of lead and wood, and cutting the sheet into a series of pairs of narrow laths a, b, c ... as indicated in Fig. 4, the cuts for the successive pairs being increasingly inclined to the laminations. The inclination of the cuts gives the lead strips in each lath a uniform orientation which is correct only for the central strip ; but before assembling the laths into the grid form indicated in Fig. 2, each is pressed in one of a set of dies such as is shown in Fig. 5, with properly inclined pressure-ends 47, 53 so as to cause the individual strips in the lath to assume the correct angles. The laths are joined together by an adhesive such as a cellulose paste, thus producing a grid in which the passages in a, Fig. 2, are at right-angles to the finished grid, and those in the pairs b, b, c, c ... are successively increasingly inclined to the passages in a, The grid may be mounted in a frame with a metallic rim, and its faces may be protected as with varnish, cloth, or paper. The grid is not necessarily flat.

Title: Improvements in or relating to means for preserving an electric motor against the action of an injurious surrounding medium whilst ensuring lubrication and cooling of the motor
IPC: H02K9/19
Filed: 1922-02-03
Abstract: 197,014. Longue, R. Feb. 3, 1922. Addition to 159,862. Motors, cooling; insulation; casings.- In a motor fitted with oil or other liquid to protect it from the action of an injurious surrounding medium and having means for equalizing the pressures of the internal and external media as described in the parent Specification, the bearings are enclosed in oil-filled casings communicating with a chamber having a movable or distortable wall for equalizing the pressures of the lubricating oil and surrounding medium independently of the liquid in the main motor casing. The liquid in the main casing may be separately cooled. In the form shown in Fig. 1, the bearings a are contained in casings c filled with lubricating oil and communicating with a vessel having a piston h whereby the oil pressure is equalized with that of the surrounding medium. The oil which fills the motor casing d, and which is unsuitable for lubrication, is equalized in pressure by another piston i. For exact equalization of the pressures in the casings c, d and the surrounding medium, the axes of the pistons are arranged in the same horizontal plane as that of the motor shaft. Fig. 3 shows a form in which equalization occurs at the contact surface between the lubricating and insulating oils and the water surrounding the motor. The bearing members j communicate by pipes l, m with a chamber k, and the motor casing d communicates at s with another chamber q. The chambers k, q are connected at o, t with tanks n, r into which the surrounding water also enters through pipes p, u. The contact surfaces between the oil and water in the tanks n, r is in the same horizontal plane as the axis of the motor shaft. When the motor works in a deleterious atmosphere, this atmospheres has access to water which rests on the oil in the tanks n, r, or the tank r may be omitted. The oil may be cooled by a water circulation in the space between the motor casing v, Fig. 5, and a corrugated cylindrical liner x, ducts z, w and baffles 2, 3 being provided to direct the oil as shown by the arrows. Alternatively, the oil may flow in contact with a waterpipe coil in the motor casing or through a cooling device which is independent of the motor.

Abstract: 643,106. Hydraulic brakes. GOODRICH CO., B. F. Feb. 5, 1948, No. 3452. Convention date, April 20, 1944. [Class 103 (i)] [Also in Group XXIX] A valve of the type used in hydraulic braking systems to maintain a certain minimum pressure in the brake cylinders after the master cylinder has been operated to release the brake shoes is constructed so as to provide a much more rapid reduction of pressure down to the minimum required, than that provided by the usual poppet valves. The supply from the master cylinder is led in by a central port 36 and deflects a diaphragm 30 against the action of spring 18 so that the hydraulic fluid is able to pass on to the brake cylinders by way of annular recess 39 and outlet connection 38. The increased area of flow due to the large valve seat 34 provides for a rapid reduction of the pressure down to that at which the spring 18 and cap 16 shuts the valve.
